SAN FRANCISCO -- Brian Wilson was back on a mound in San Francisco last week.

The former Giants closer threw at USF on Friday as he continues to rehab from a second Tommy John surgery. Wilson still sports his trademark bushy beard, making him easy to spot, even in a city as eclectic as San Francisco.

Wilson has been hard to find since parting ways with the Giants in the offseason. When he wasn't healthy enough to make a team this spring, Wilson continued the rehab process in Hawaii. He did not return to San Francisco for a World Series ring ceremony in April but has been seen around town this weekend. Photos on Instagram showed him playing disc golf at Golden Gate Park on Saturday.

According to ESPN's Buster Olney, Wilson intends to hold a showcase event for scouts around Aug. 1 in hopes of securing a big league job for the season's final two months. It is yet to be seen how many teams show interest, but a league source said the Giants are one of the clubs that have kept tabs on Wilson during the rehab process.
